How Sonar Works

Sonar technology is based on sound waves. The Matrix Fishing System uses sonar to locate and define structure, bottom contour and composition, as well as depth directly below the transducer.

Your Matrix Fishing System sends a sound wave signal and determines distance by measuring the time between the transmission of the sound wave and when the sound wave is reflected off of an object; it then uses the reflected signal to interpret location, size, and composition of an object.

Sonar is very fast. A sound wave can travel from the surface to a depth of 240 ft (70 m) and back again in less than ¹⁄₄ of a second. It is unlikely that your boat can "outrun" this sonar signal.

Your Matrix Fishing System will either have Single Beam, DualBeam PLUS™ or QuadraBeam™ sonar. Find the correct sonar description that applies to your unit.

Single Beam Sonar

Your Matrix 10, 12 or 20 uses a 200 kHz single beam sonar system with a 20° area of coverage. Depth capability is affected by such factors as boat speed, wave action, bottom hardness, water conditions and transducer installation.

DualBeam PLUS™ Sonar

Your Matrix 17 or 27 uses a 200/83 kHz DualBeam PLUS™ sonar system with a wide (60°) area of coverage. DualBeam PLUS™ sonar returns can be blended together, viewed separately or compared side-by-side. DualBeam PLUS™ is ideal for a wide range of conditions - from shallow to very deep water in both fresh and salt water. Depth capability is affected by such factors as boat speed, wave action, bottom hardness, water conditions and transducer installation.

QuadraBeam™ Sonar

Your Matrix 37 Fishing System uses QuadraBeamTM sonar. QuadraBeamTM sonar provides an extremely wide 90° area of coverage. QuadraBeamTM starts with two 45° 455 kHz beams for a continuous 90° of uninterrupted side to side coverage to 160 feet. These Side Structure locating beams reveal fish and structure to the left and right of your boat near the bottom. For structure directly below your boat, QuadraBeamTM uses DualBeamPLUS™ technology.
